Description

[Detailed description of the invention] The present invention relates to a vehicle transport vehicle for multiple vehicle types.

In general, a vehicle transport vehicle consists of a lower deck on the chassis and an upper deck that can be adjusted up and down, and within the legal height and length regulations, a total of six domestic small vehicles can be carried, three on the top and three on the top. It is ready for loading.

On the other hand, as a result of various improvements made to accommodate as many cars as possible, a model with a middle deck between the upper and lower decks that can carry up to seven domestically produced small passenger cars is now in practical use. It has the disadvantage that it cannot efficiently load more medium-sized passenger cars, small trucks, etc., and if it tries to load more and more efficiently, it has the disadvantage that the number of hydraulic cylinders increases and the loading platform becomes complicated.

To explain this further, in a known vehicle carrier having a front upper deck, an intermediate upper deck, and a rear upper deck, the rear end of the intermediate upper deck and the rear upper deck are used for loading medium-sized passenger cars and light trucks. It becomes necessary to separate the front end, but if the separation is performed in this way, a problem arises in that the rear upper deck loses support from the intermediate upper deck and turns backward.

The present invention aims to solve these problems by eight simple measures.

Hereinafter, the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes the chassis of a vehicle transport vehicle.The rear of the chassis 1 is supported by wheels 2, and the front thereof is connected to a tractor 3.

The front portion 1a of the chassis 1 is raised in a stepped manner, and guide rails 4 each having a U-shaped cross section are established on both sides of the front end thereof in a manner such that they face each other with their grooves facing inward.

Similarly, guide rails 5 are also provided on both sides of the rear end of the chassis front section 1a.
are established facing each other with their grooves facing inward.

A front upper deck 7 is provided between the guide rails 4 and 5.

Guided members 7a protruding from both sides of the front part of this deck 7 are slidable up and down within the grooves of the guide rail 4.
Therefore, the front part of the deck 7 is guided by the guide rail 4.

One end of a wire 8 is connected to the front part of the deck 7, and this wire is connected to the boot IJ 9, 1 supported by the guide rail 4.
0, and the other end is connected to the tip of the piston land 11a of the hydraulic cylinder device 11.

Therefore, as the cylinder device 11 expands and contracts, the front portion of the deck 7 moves downward or upward.

The rear end of the deck 7 is free without being guided by the guide rail 5.

One end of a wire 12 is fixed to this rear end, and this wire 12 is hung around pulleys 13, 14, and 15, and the other end is hidden behind the hydraulic cylinder device 11 and is not shown in the figure. is connected to the tip of the piston rod 16a of the hydraulic cylinder device 16 in the opposite direction.

Therefore, as the hydraulic cylinder device 16 expands and contracts, the rear part of the deck 7 moves downward or upward.

A column 19 having a series of stop pin insertion holes 18 is integrally provided in front of the guide rail 5 at a distance therefrom.

Therefore, after operating the hydraulic cylinder device IL16 to appropriately determine the height and inclination of the deck 7, the position of the deck 7 is fixed by inserting a stop pin into the lower side of the deck 7 from the stop pin insertion hole 18. be done.

A guide rail 21 is also provided in the middle of the chassis 1,
This guide rail and the post 22 at the rear thereof are integrally connected to the guide rail 5 by a longitudinal connecting beam 23.

Guided members 25a protruding from both sides of the front end of the intermediate upper deck 25 are engaged in the inner groove of the guide rail 5, and the front portion of the deck 25 is guided by the guide rail 5 and can freely move up and down. It becomes.

The guided member 25a is fixed to both ends of the cross member 26 as shown in FIG.
The tip end edge of the deck 25 is pivotally attached to the rear part of the deck 25 by a pin 27.

Therefore, the deck 25 is angularly displaceable with respect to the cross member 26.

As shown in FIG. 1, the upper end of a piston rod 29a of a hydraulic cylinder device 29 is connected to the guided member 25a, and the front portion of the deck 25 moves up and down as the cylinder device 29 expands and contracts.

The rear part of the deck 25'' reaches a position between the opposing columns 22.

In order to determine the height of the rear part of this deck 25, the support 22
A column 3 having a series of stop pin insertion holes 30 in front of the column 3.
1 is permanently installed.

Therefore, by inserting a stop pin into any of the stop pin insertion holes 30 and applying it to the lower side of the deck 25, the height of the rear part of the deck 25 is fixed.

Note that the means for vertically moving the rear part of the deck 25 will be described later.

In the inner groove of the guide rail 21, there is a middle deck 3.
Guided members 33A on both sides of the front end of 3 are guided to be movable up and down, and one end of a wire 34 is fixed to the guided members 33A.

This wire 34 is passed through the IJs 35 and 36, and the other end is fixed to the connecting beam 23 at a position indicated by 37.

The pulley 36 is the piston rod 3 of the hydraulic cylinder device 38
The front end of the deck 33 is supported by the tip of the deck 8a, so that the front end of the deck 33 is lowered and raised by the expansion and contraction of the hydraulic cylinder device 38.

A hydraulic cylinder device 40 is interposed between the rear end of the middle deck 33 and the chassis 1, and its lower end is connected to the chassis 1.
Further, the upper end is pivotally mounted near the rear end of the deck 33.

Therefore, the rear end of the deck 33 moves up and down as the hydraulic cylinder device 40 expands and contracts.

In order to fix the height of the rear end of the deck 33, a column 42 having a stop pin insertion hole 41 is provided.

A slide column 44 is attached to the rear end of the chassis 1 by a pin 43.
An outer column 44a is pivotally connected thereto, and the tip of an inner column 44b slidably fitted into the outer column 44a is pivotally attached to a rear upper deck 46 by a pin 45.

On the other hand, a hydraulic cylinder device 49 is provided between the brackets 1-47.48 fixed to the outer column 44a and the inner column 44b, and as the hydraulic cylinder device 49 expands and contracts, the hydraulic cylinder device 49 and the slide column 44 are moved. They expand and contract together while maintaining a parallel state, and the rear upper deck 46 is displaced up and down.

The rear end of the intermediate upper deck 25 and the rear upper deck 46
Usually, there is a relationship as shown in FIG.

That is, a cross beam 52 is pivotally attached to the front end of the rear upper deck 46 by a pin 51, and a claw-like projection 53 protruding from the front side of the cross beam is connected to the intermediate upper deck 25.
It is in contact with the lower surface of the protrusion 54 protruding from the rear end.

Therefore, the cross beam 52 and the rear upper deck 4
The rear part of the middle upper deck 25, the front end of which moves up and down, is not fixed to the projection 5 unless it is fixed by a stop pin.
It moves up and down while being supported by 3.

The vertical movement of the cross beam 52 is performed by a hydraulic cylinder device 56 (FIGS. 1 and 4), which will be described next.

The cylinder 56b of the hydraulic cylinder device 56 is connected to the support column 31.
A pulley block 57 is fixed to the lower end of the piston rod 56a, and upper and lower boops IJs 58 and 59 are provided thereto.

Then, a wire 60 whose one end is connected to a fixed part such as the hydraulic cylinder device 56 is hung from the lower side of the pulley 58 and guided upward, then hung around a pulley 61 supported by the column 22 and guided downward, and similarly. After being hung on the boo 162 supported by the column 22, it is further hung on the pulley 59 from above, and the other end is connected to a fixed part such as the column 31.

Therefore, as the hydraulic cylinder device 56 expands and contracts, the cross beam 52 and the front portion of the rear upper deck 46 are vertically displaced, and the rear portion of the intermediate upper deck 25 is also displaced in the same direction.

In the above configuration, for example, the state when domestic small cars are loaded is as shown in FIG. 1, and seven cars are loaded using the middle deck 33 as well.

These seven vehicles are C1, C2, C3, C4, C6
, C6, and C7.

These vehicles are loaded in the order of suffixes 1 to 7 attached to the symbol C, and the order is as shown in FIGS. 5A to 5.

First, as shown in Figure 5A, the three upper decks 7.2
5. Tilt the 46 downward to the rear, place the footboard 65 at the rear end of the chassis 1 (door hook), and place the vehicle in the order of C1, C2, and C3.

Next, as shown in FIG. 1B, the three upper decks and the middle deck 33 are raised upward to create a space for the vehicle to be placed on the lower deck on the chassis 1.

Then, after hanging the inclined running plate 66 and placing the vehicle C4 on the front part of the chassis, as shown in FIG. Lower the vehicle, place the vehicle C6 on the middle deck 33 using the inclined passage plate 67, and finally move the vehicle C7 onto the middle deck 33 as shown in the same figure.
After loading, the upper deck 7, 25, 46 and the middle deck 33 are lowered to a point where they do not touch the automobile, and the loading is completed.

Unloading is done in the reverse order.

Figure 6 shows the situation when six medium-sized passenger cars are loaded.

In this case, the middle deck 33 is not used, and the vehicles are loaded in the order from beam D6 to D6 as shown in FIGS. 7A to E.

Also, as shown in figure A, the upper three decks are 7°25.4
6 so as to be lower to the rear, hang the footboards 65 on the rear end of the chassis as shown in Fig. 5A, and lower the front upper deck 7.
Vehicle D1 is placed on top.

Next, as shown in Figure B, the rear of the front upper deck 7 is raised and the vehicle D2 is placed on the intermediate upper deck 25 until the front of the vehicle D2 enters below the rear of the vehicle D1. After raising the rear of the deck 25 and fixing it to the support column 31 with a stop bin, the vehicle D3 is loaded onto the rear upper deck 46.

At this time as well, the front part of the vehicle D3 comes to fit under the rear part of the vehicle D2.

Next, the hydraulic cylinder device 56 is operated to lower the cross beam 52 and also lower the front portion of the rear upper deck 46.

As a result, the state shown in FIG. 7C is obtained.

As above.

Raise the rear part of the intermediate upper deck 25 and lower the rear upper deck 4.
When trying to break the contact with the front part of 6, with the conventional one,
There is a problem that the rear upper deck 46 is reversed clockwise in the figure, and the front end of the rear upper deck 46 needs to be supported from above by the rear end of the intermediate upper deck 25.

In contrast, in the present invention, the front end of the rear upper deck 46 is movable up and down by the hydraulic cylinder device 56.
Cross beam 52 that can be fixed in any vertical position
Therefore, even if the rear upper deck 46 tries to reverse backwards, a reaction force is generated by the cross beam 52 and no reversal occurs.

The state shown in FIG. 7C is a state in which the three upper decks and middle deck 33 are raised so that the vehicle is placed on the chassis 1, and in this state, the inclined passage plate 66 is used to move the vehicle D4 as shown in the figure. Then, remove the threading plate 66 and see E in the same figure.
Vehicle D5. Load the D6 and lower the upper and middle decks until they do not touch the vehicle to complete loading.

Unloading can be carried out in the exact opposite manner to that described above.

As described above, in the present invention, even if the rear end of the intermediate upper deck is separated from the front end of the rear L deck, there is no fear that the rear first deck will flip backwards. It becomes possible to set each deck, especially the rear upper deck, to the state for loading.
